Top 10 Crown Molding Materials

Traditionally, crown molding has been made from milled hardwood and plaster. Wood crown molding can be found and made from several hardwoods such as hickory, ash, poplar, alder, cherry, maple, mahogany and oak. Wood crown molding enriches the character of any interior as it frames your ceiling and complements your decor. There are many styles available and you can find many of the traditional styles, such as acanthus, grape and oak leaf motifs and shell. Wood crown molding will certainly add classic detail to any room.

On the down side, hardwood moldings can be quite expensive. Forest resources are limited. The softwood moldings require more time and care to install and finish, although it is less expensive than hardwood. Wood moldings shrink and swell with humidity, they can be damaged by water, it is combustible, it can be damaged by rot and insects, it can crack, it requires mitering and coping skills, it may split and splinter when nailed or cut, and wood molding must be sanded and primed prior to finishing. These disadvantages may outweigh wood’s good points for many.

Renewed interest has been growing in decorative ornamental plaster. Decorative plaster molding can be found in all styles. Ornamental plaster crown moldings do not shrink, burn, warp or produce toxic fumes. Ornamental plaster can be formulated in a wide range of compositions to yield finished products which include a range of properties. They are versatile, safe, stable and economic. Ornamental plaster, although an excellent product, can be costly to install. Although it is no longer required to be manufactured in place, skilled craftsmen are in short supply and it has become almost a lost art.

MDF crown molding, a wood-based composite material that uses wood fibers with a synthetic resin, is another example of how a builder or decorator can accent any room or hallway. MDF is environmentally safe and requires less preparation. It is often primed to a smooth surface which can then be painted with any high quality latex or oil paint. MDF won’t split when cutting, is resistant to warping and is consistent in size and shape. However, during installation of MDF, nailing creates blemishes that will require repair, by hand, prior to finishing. Although it is a less costly alternative to other materials in use, most professionals do not recommend its use.

Polyurethanes are found in many items. They are used in resins, adhesives, fibers, foam padding and insulation. They come in several forms, such as rods, sheets and liquids. Polyurethanes are frequently used as an alternative to such materials as wood, plastics, metal and rubber. And for good reason. Polyurethanes are resistant to wear and tear, weather, impact, scratching and erosion. They are also more cost-effective as an alternative as well.

Other uses for polyurethanes include: fibers, seals, gaskets, condoms, hard plastic parts, carpet underlay and sealants. Items such as domed ceilings, moldings and ceiling medallions are easier to construct of polyurethane foam rather than wood. In fact, polyurethane is considered to be the best replacement for plaster. It’s low cost, lightweight and anything you can do to wood, you can do to polyurethane. It is easy to install, can be used either interiorly or on the exterior and is available in the widest range of products.
